A low-cost three-dimensional laser surface scanning approach for defining body segment parameters
Body segment parameters are used in many different applications in ergonomics as well as in dynamic modelling of the musculoskeletal system. Body segment parameters can be defined using different methods, including techniques that involve time-consuming manual measurements of the human body, used in conjunction with models or equations. In this study, a scanning technique for measuring subject-...
متن کاملEstimation of Body Segment Parameters from Three-dimensional Gait Data Using Optimization
Body segment parameter (BSP) values are needed to perform forward and inverse dynamics analyses of gait. These parameters describe the mass, mass center, and moments of inertia of each body segment and are typically estimated from scaling rules developed from cadaver studies. However, estimated BSP values from different studies can vary by more than 40% (Pearsall and Costigan, 1999), plus there...
متن کاملSubject-specific body segment parameter estimation using 3D photogrammetry with multiple cameras
Inertial properties of body segments, such as mass, centre of mass or moments of inertia, are important parameters when studying movements of the human body. However, these quantities are not directly measurable. Current approaches include using regression models which have limited accuracy: geometric models with lengthy measuring procedures or acquiring and post-processing MRI scans of partici...
متن کاملA Method for Direct Measurement of the First-Order Mass Moments of Human Body Segments
We propose a simple and direct method for measuring the first-order mass moment of a human body segment. With the proposed method, the first-order mass moment of the body segment can be directly measured by using only one precision scale and one digital camera. In the dummy mass experiment, the relative standard uncertainty of a single set of measurements of the first-order mass moment is estim...
متن کاملQuantitative evaluation of anterior segment parameters in the era of imaging.
PURPOSE To review the parameters for quantitative assessment of the anterior segment and iridocorneal angle and to develop a comprehensive schematic for the evaluation of angle anatomy and pathophysiology by high-resolution imaging. METHODS The published literature of the last 15 years was reviewed, analyzed, and organized into a construct for assessment of anterior segment processes. RESUL...
